FOLDING COMBINATION POCKET-SQUARE.

Specification of Letters Patent.

Patented Sept. 4t, 1917.

Application filed March 23, 1914. Serial No. 826,567.

To all whom it may concern of the invention is to provide a measuring device of this character by means of which a line may be drawn or scratched. across a board or other object at right angles to the.

edge thereof.

Another object is to enable a line to be drawn or scratched across a board or other object at any desired angle with respect to the edge thereof.

Another object is to enable the device to i be used as a gage to mark a line along any surface parallel with the edge of such surface, and at any desired distance from the edge of such surface within the limits of the capacity of the instrument, or to find the 1 Another object is to provide a blade slid ably and pivotally supported by the beam of the device to enable the device to be used as a square in a corner or as a bevel square, or to form an extension of the beam at an angle thereto or in line therewith for use as a straight edge or for measuring.

. Another object is to enable the device to be used as insidecalipers.

Other advantages and objects will be i brought out in detail in thefollowing description.

Referring to the drawings: Figure l is a plan view of the devlce folded up for carrying in the pocket.

Fig.8 is a perspective view of the pivoting portion of the marking arm.

The device. comprises a beam 1, which perspective view of the sliding consists of two plates 2 and 3, which are secured together in any desired manner, and spaced apart to form slots to receive a marking blade 4 and a slotted extension blade 5. Marking blade 4 has a circular boss 6 which 1s pivoted in the lower sideof a block. 7, which is slidable in a slot 8 in the upper plate 2, the block 7 having flanges 9. which projectunderneaththe plate 2 to retain the block in position. A knurled thumb screw 10 is screwed into the block 7, and the thumb screw has a projecting pin 11, which extends through the blade 4 and has a pointed end 12 which is adapted to engage in any one of a series of conical depressions 13 formed in the lower plate 3. The thumb screw has a shoulder 141: which is adapted to bear against the boss 6 to exert a downward pressure on the same and clamp the blade A in the position in which it may be set. The conical depressions 13 are arranged at intervals corresponding with certain angular positions of the marking blade 4, to insure accuracy in setting at such angles. The object of these depressions is to obviate the necessity of a close reading of the scale by setting the blade for these definite positions, and positively insuring an accurate setting by acting to move the center of the pointed end of the pin 11 and connected parts .into exact position as the screw 10 is tightened. Thus,

. graduations 16 for indicating the distance of the marker from the beam. There are certain distances from the marker to the beam at which the marker is very oftenused and the graduations I have shown in the series 16 are for these particular distances, but it will, of course, be understood that as many graduations as desired may be employed. The plate 2 is also provided with a series of graduations 17 for indicating intermediate positions of the block and corresponding angles of the marking blade 4. The plate 2 is also provided with a series of graduations 18 for ordinary measuring purposeswhen the dev ce 18 used as a rule.

The marking blade 4 is 'pivotally secured at 19 to a link 20, the link20 being pivoted at 21 to the beam 1. "The outerend' ofthe marking lolade may be equipped with any preferred form' of marking device, for example, the reversible. screw having a pointed scratch end 23 and at its other end having a detachable pencil point 24. .The'

markingblade 4 is also provided alongits inner edge with a series of notches 25, which are adapted to be engaged by. the

fpoint of the pencil or scrat'ch'to mark t other points than the regular marking screw 22, or for panel gaging parallel wlth the edge of the object.

ion the lower side of the beam 1 is a fiange\26..wl'1ieh serves to rest against. the edge of. the. board or other object to hold the beam parallel with the edge of the board or object, and. thebeam 1 is cutaway at 28 (to rece ve the screw 22 and allow the marking blade ito be folded in to bring the marking point 23 a8 close to the flange 26 as pos Slb1Q, SO that when the mark is made, it will extend practically to the edge of the board. This also permits an object with an acute corner to be received between the link 20 and outer portion of blade at, as the corner of the beam, being cut away, does not protrude intothe space between the. bladeand link. The

length of thelink 20 between its pivotal points corresponds to the distance between thepoint 19 and marking point 22, and also to the distance between pivotal point 19 and center of thumb screw 10 so that by moving the lower endof themarking blade 4: along the slot/8, the marking pdint 22 is: always compelled to move in a line at right angles to the beam '1, this line being indicated by f dotted line 28 Fig. 2. Thus, when itis desired to mark a board or other-object at right angles to its edge, thebeam 1 is laid ontop and atthe edge thereof with L the flange 26bearing against the edgeandi thenthe marking point 22 is grasped, the thumb rscrew 10'having be'enloosened and drawn in a: direction away from the beam, thus marking a line ontheboard oriobject at right angles to the edge thereof. If it is desired to mark a line parallel with the edge of the board, the blade may be adjustedto v.olace the marking screw 22 at the desired wdistancefrom the edge of the board and then theithumb screw 10 tightened, andthen the beam 1 may be moved longitudinally along .:the edge of theboard to cause the marking screw 22 to marktheboard on a line par allel with the edge thereof. In. thislatter operation the marking may be performed if Idesxred by inserting-the point of the pencil or scratch-1n one of the notches 25 in theblade 4 and then moving the beam alongthe edge.

If itis desired to draw a line at a certain i n le. t the e e 0 th oa d. r ebiec the blade t may be adjusted to any position and the thumb. screw. ,10 tightened, and then in marking, the device may be drawn along the edge 29 of the blade 4. Thisadjustment of the blade 1 may also be employed in determining-the angle of a board or object already cut.

The blade 5--bei ng'- slotted :may be adjusted in any angularposition withrespect 1 to thebeam 1 and retainedin such position by clamping screw 30,.which is located at the corner: of the beam so. that itw'ill. bring the edge 81 of the blade 51in. perfect line with the edge of beam. l-when the blade 5 iseX- tended as shown'in.Fig-2,.andqwhenthe 1 blade is adjusted intoflthedotted line positions it brings the edge 32against ablock 33. which is between thezplates2 and-3 and acts as astop to hold the bladeperfectly atright anglesltov the beam,thel blade to be set at any angle as indicated indotted linesi34c for use as a bevelsquare. v1dedw1th graduatlons as ishownsto, act as a.continuation 2of..:the. graduations 18 on beam 1.

The flange 26 is prefera made of suflibe used as a clinoi'neteru Thus, byplacing the beamrso that the levelzindicates. alevel POSQUOH' andby. then .ra1siug1 the marking 'blade'l .to the. .1ncl1nat1on of the surface or line to be measured,.the angle is indicated on the blade.bythepositionuof the. bar 15.
